Abstract: The chemical effects created by the isomeric transition of $^{129m}$Te to the ground state were investigated on the organo-metallic compound $^{129m}$Te ($C_{6}H_{5})_{2}$ The results are compared with the ones from the (n, $\gamma$)-reaction on Te ($C_{6}H_{5})_{2}$. The separation of the new chemical Te-compounds formed as a consequence of the nuclear process was achieved by adsorption chromatography on $Al_{2}O_{3}$. In many, but not in all cases, thenuclear transformation causes bond rupture. Practically identical labelled Te-compounds were observed for both the isomeric transition and the (n, $\gamma$)-process. The percentage yield distribution however shows certain characteristic deviations. A reaction mechanism which may explain these observations is discussed.lt is concluded: the charge developed by the Auger process following internal conversion causes coulombic repulsion and gives a tellurium recoil atom, which, loosing its kinetic energy by collisions with neighbouring molecules, creates a reaction zone of excited molecules, radicals and ions, and the reactivity is mainly influenced by it.
